the diagram shows fossil a and fossil b. assume that fossil a is typically found in rock layers that are far above the rock layers containing fossil b. fossil a fossil b based upon the positions of fossils a and b, which inference is best? fossil a must have evolved from fossil b. fossil b existed in greater numbers than fossil a. fossils a and b lived during the same period of geologic time. fossils a and b lived during different periods of geologic time.

Answer

Brief Explanations:

In geology, fossils in different rock - layer depths usually indicate different time periods of existence. Since Fossil A is in rock layers far above Fossil B, they likely lived during different periods of geologic time. The position in rock layers is a key indicator of the relative age of fossils.

Answer:

Fossils A and B lived during different periods of geologic time.
